1. Introduction & Application

FT-ZLS High-end Smart Type Automatic Interfacial Tension Testing Kit equipped with large-size touch screen, adopting ASTM D971 "platinum ring method", tests various liquid interface tension (interface between liquid and air) and also that between mineral oil and water(interface between liquid and liquid) by means of automatic control of internal microcomputer under circumstances of non-equilibrium. Testing only requires pouring liquids into sample cup and then pressing "start" button. Then tester can finish total test and calculate tension value automatically according to concrete input parameters.
